Temporal bone involvement by prostatic adenocarcinoma: report of two cases and review of the literature.

Although axial bone and cranial metastases are common in patients with prostatic carcinoma, temporal bone involvement is rare. We report 2 cases of prostatic adenocarcinoma with temporal bone metastasis and review the relevant literature. One case had a 3-year history of a prostatic carcinoma, whereas in the second case the temporal bone metastasis was the initial presentation. Awareness of the possibility of temporal bone involvement by prostate carcinoma and application of immunohistochemical studies will help to arrive at the correct diagnosis.
